Randy,
I would recommend the Dremel Multi Max with the round blade to split your cut lines. It can make a very thin surgical cut and I don't think it will chip the Bondo. See the first photo of my post #90 under "Tornado GT40 in Texas". I highly recommend it for all fiberglass work using the round blade, the rectangular blade, or the sanders. I have really used it a lot.
I also noticed that you do not have the latches installed or any rubber spacing between the sill cover and the rear clip. You might want to secure that before you finalize the lines for the air inlets, etc. The Tornado build calls for a 1/4" strip of rubber between the sill and rear clip. I thought that was too large of a gap so I attached a 1/8" fiberglass spacer to the rear clip and used a 3/16" rubber strip. When the latches pull the rear clip down firmly, then I will have a 3/16" gap which I think will look better. I have some extra 3/16" rubber if you want some.
I admire you for going this extra step. I hope I don't get tempted to do the same!
